To all whom t may concern:

Be it known that I, BYRON B. GoLDsMrrH, a citizen of the United States, residing atY New York, in the county of New York and State of New York, have invented certain new and useful Improvements in lnk Cartridges; and I do hereby declare the followinfr to be a full, clear, and exact description of the invention, such as will enable othersl skilled in the art to which itappertains to make andA use the same.

The present invention relates to a new and improved means for producing inkcon-v veniently, rapidly and efficiently. Many different devices have been tried for producing ink by the simple addition of waterfto the ink-producing materials. rlhesey have either been contained in special receptacles, or have been` in the form of tablets to be dissolved in water. 0f these methods the only one which has survived is the ink tablet, as the former did not produce a suitable ink. The disadvantagev ofusing the ink tablet is readily understood when one considers that to makelink from ink tablets itis necessary to take a measured amount of water foreach tablet and place both in a suitable receptacle and agitate untilftherehas been complete solution. 'ln other words, it almost amounts toas much-trouble ina small way as the manufacture of liquid ink does on a. large scale. The consumer becomes the ink-y For this reason ink tabletsk manufacturer. are used very little. The desire-to find substitutes for the liquid ink of commerce, arises from three disadvantagesl it' has: Firstly, it is bul-ky and takes up much space in the factory, on the railroads, and in the dealers stock. Secondly, it is shippedin glass and there is considerable expense in packing safely, notwithstanding which breakages cannot be avoided,V Thirdly, it cannot be shipped in winteras it freezes, ruining the ink or the bottles or both". By

the use of my invention it is possible for any unskilled person to produce ink of the linest qualityv almost instantanefmsly.l

The basic principle of this invention resides in supplying narrow passages for the water wholly or partly lined withv ink pre. ducing material, which passages. are arti.

iicially' constructed with such a definite relative proportion between their diameter and length that, as the water passes through them, it necessarily has time to take up the required amount of material toproduce a satisfactory ink. The use of a single channel would beI within this principle of conf struction, in which casel if'the channel is wide enough to have the liquidiiow rapidly it would have to belong enough to allow the liquid to dissolve suiiicient material, or if' the channel is narrow the liquid would flow more slowly and the channely need not be so long. It is a little simpler, however, to employ a number of passages.

The general principle underlying this invention is capable ofjbeing carried out in a variety of ways, somev of which are set forth in certain copending applications for Letters Fatent. rIrhere claim ed herein that general form or embodiment wherein themeans for converting water into ink consists ofa group of bodies separated by one or more` narrow percolating passages Vof definite diameter, some or all of which bodies'are providedv on their surfaces with ink-producing material; p

percolating f passages havingl the characteristics already set-forth herein.

A few ofthe many possible specific embodimentsof the invention are.y illustrated in the accompanying drawings, wherein Figure l isa vertical sectional view o-f amodification affording a central ydipping space, Figures 2 and 3 are perspective views of two forms of .discs capableof use in; said modifi cation, Figure l isa plan view of another modification, Figure 5 is a vertical sectional viewof another form, Figure 6 isa perspective viefw, of another -modificatiom Figure 7 is a partial vertical sectional l view lof a further modification, Figure 8 is a perspective view of one of the discs employed in the last named, form, Figure 9 Aisa plan View of the form shown in Figure 5, Figures 10l to 14 are pla-n views of other forms, Figure 15 is a vertical section of a further modification, and Figure 16 is a perspective view of the form of disc shown in Figure 15.

lt is to be understood that the passages or channels employed in the devices actually manufactured will not be exactly as shown in the drawings. As already stated, the actual diameters and lengths of the passages will be experimentally determined for each particular type of device and character of ink. Y f

ln F iguresl and 2 are shown a hollow cylindrical support 10`having openings 11, upon which are supported discs 12 made wholly 'por partlyof ink-.producing material, andresting on the flangev13. Theseare preferably spaced apart, as by the projections 14 on lsaid discs, toform' percolating passages between the discs.r As shown in Figure 3, the discs may be made corrugatedl or of wavy irregular form, therebyforming the percolating passages vbetween them. This modification is especially adapted for use by immersion in a body of water which will lind its way into the center of the cylinder 10 which will serve as a dipping space for'the pen. rlhe invention is not limited to this mode of use, however.

1n the form shown in Figure 4c, the inkproducing bodies 15 take the form of plates, spaced apart, as by means of wires or rods 16, and held together by the casing 17preferably of cylindrical form. While it is preferred to use ink-producing material upon the surfaces of all of the plates 15, thisv is not essential to the invention.

ln the form `shown in Figures 5 and 9 the bodies between which the percolating spaces are formed take the form of rods 18 supported by grids 19 placed transversely 4in a tubular casing`20. As shown by the double circles in Figure 9 these rods may have a neutral core with a facing of .inkfproducing material. Water may be poured into one end of this device, and theink will emerge ,l from the other end.

Another form which can be used in the same way is shown in Figure 6. Here there are employed a group of concentric tubes 21, some or all of whichare faced with ink'- producingl material. They are spaced apart in any convenient manner to produce percolating passages, as for instance, by rods or wires 22.

ln the form shown in-Figures 7 and 8 the percolating spaces exist between successive discs 23, supported within a tube 211 and spaced apart'by .rings 25 within the tube. The discs are provided with perforations 26 located on opposite sides of the tube,'so that 'when water is poured intotheI-tube at one end it will be caused to fiowin a narrow fiat stream betweenV all the pairs of discs successively.

'of use in different ways.

greater. number will be used and they will be placed closer together, as shown at 30in Figure V11. The central core is not necessarily cylindrical. For instance, a core 31 having longitudinal fluting may be vused,`as shown in Figure 12. ln this case spacing rings 32 will be used `at the two ends of the device. As'shown in Figure 13, still another ceV varient of this type is produced by grooving the core longitudinally, producing. longi? tudinal grooves 33.

Figures 15 and 16 show another mode of assembling the parts. Here the ink-producing bodies 34, in ytablet form, are supported. between discs 35 fitting within a casing 36. These supporting discs are perforated as shown at 37 and have ridges -38 or other` projections against which the tablets 34: rest, so as to form percolating passages above, below and around said tablets, which communicate through the openings 37 In the form shown in Figure 141, the percolating passages are formed between the parallel rods 39, formed of or covered with ink-producing material, and held together by means of a iexible spiral envelope 40, secured in any desired manner around them.

It is to be understood that the various forms of cartridge herein shown are capable For instance, they may be made very cheaply; with a thin coating of ink-producing material on the various bodies, which maybe thrown away after being used once or twice. Or again, the water Vmay be supplied more' or Vless rapidly according asfthe passages are narrower or wider; or it may be made to pass through the passages more than once.

lt is clear from thev few examples above set forth that the present invention is capable of many modifications, and that its scope is not to be limited to the details herein shown and described.

What is claimed is- 1. An ink cartridge consisting of a groupV percolating passages of definite prede-c.
